Description
InWater Tech Aluminum Frame Diffuser 600mm (24″)
High Efficiency Ceramic Oxygen Diffuser for Freshwater Aquaculture
The InWater Tech Aluminum Frame Diffuser 600mm is a premium-quality ceramic oxygen diffuser engineered to deliver efficient oxygen transfer into water across a wide range of aquaculture and water treatment applications. Designed specifically for freshwater systems, this robust aluminum frame diffuser creates an ultra-fine micro bubble pattern that maximizes dissolved oxygen absorption while reducing oxygen consumption and operating costs.
Manufactured using high-grade ceramic technology, the diffuser generates consistent micro bubbles that stay suspended in the water column longer than traditional coarse bubble systems. This increased contact time significantly improves oxygen transfer efficiency, helping maintain stable dissolved oxygen levels in intensive aquaculture systems.
The InWater Tech 600mm diffuser is widely used in:
- Recirculating Aquaculture Systems (RAS)
- Fish hatcheries
- Fingerling production systems
- Live fish transport and holding tanks
- Oxygenation systems
- Aquaponics
- Water treatment applications
- Research facilities
- Commercial aquaculture farms
Its durable aluminum construction provides excellent strength and long-term reliability in freshwater environments, while the ceramic diffuser element is resistant to chipping and peeling for extended service life.
Key Features
High Efficiency Micro Bubble Technology
The ceramic diffuser produces extremely fine oxygen bubbles that remain suspended in the water longer, increasing oxygen transfer efficiency and improving dissolved oxygen saturation levels.
Durable Aluminum Frame Construction
Built with a heavy-duty aluminum frame designed for freshwater aquaculture applications requiring long-term durability and dependable performance.
Resistant Ceramic Coating
The diffuser coating is designed to resist chipping and peeling, ensuring reliable operation in demanding aquaculture environments.
Integrated Check Valve System
Includes a built-in check valve to prevent backflow of water into the oxygen supply line. The valve opens automatically at operating pressures above 8 psi.
Low Maintenance Design
Easy-to-clean ceramic surface allows quick maintenance and restoration of performance if fouling occurs.
Flexible Installation
Can be installed individually or connected in multiple diffuser arrays using a common oxygen supply line.

Why Use Ceramic Oxygen Diffusers in Aquaculture?
Maintaining dissolved oxygen is critical in intensive aquaculture operations. Low oxygen levels can reduce fish growth, increase stress, suppress feeding activity, and increase mortality risk.
The InWater Tech 600mm diffuser helps operators maintain consistent oxygen levels by efficiently dispersing oxygen into the water through millions of ultra-fine bubbles. Because micro bubbles rise more slowly than coarse bubbles, oxygen has more time to dissolve into the water rather than escaping at the surface.
This makes ceramic oxygen diffusers ideal for:
- High stocking density systems
- Intensive RAS operations
- Hatchery oxygenation
- Emergency oxygen systems
- Broodstock holding systems
- Fish transport systems
- Degassing and oxygenation columns
Freshwater Applications
The aluminum frame version is specifically recommended for freshwater use where high durability and structural strength are required.
Common species include:
- Barramundi
- Trout
- Salmon
- Tilapia
- Murray Cod
- Jade Perch
- Silver Perch
- Ornamental fish species
For saltwater applications, plastic frame diffuser models are recommended.
Installation Guidelines
For best performance:
- Install the diffuser horizontally.
- Ensure the diffuser is fully submerged before pressurizing.
- Avoid placing screens or obstructions above the diffuser surface.
- Install deeper in the water column for improved oxygen transfer efficiency.
- Use appropriate oxygen regulators and flowmeters.
- Do not exceed 50 PSI operating pressure.
The included check valve helps prevent water backflow into the oxygen supply line and improves operational safety.
Maintenance
Routine maintenance helps maintain even bubble distribution and optimal oxygen transfer.
General Cleaning
- Rinse with clean water
- Use a hard bristle brush to remove biofouling
- Hose down deposits and slime buildup
Restoring Plugged Diffusers
If fouling reduces performance:
- Dry the diffuser completely
- Sand the ceramic surface lightly using coarse grit sandpaper (#40–#60)
- Remove the outer fouled layer to restore flow
Important Notes
- Avoid contamination with oils
- Avoid physical shock or impact
- Store dry when not in use
